The Zmanim<\/em> (“times” referring to the calculations of time that govern the start and end time of Jewish prayers and holidays) project is a Java<\/a> API<\/a> for generating zmanim from within Java programs. The Java Zmanim API has been ported to .NET (Jewish Zmanim Framework<\/a>) and Objective-C (KosherCocoa<\/a>). If you are a non programmer, this means that the software created by the project is a building block of code to allow other programmers to easily include zmanim in their programs. The basis for most zmanim in this class are from the sefer<\/em> Yisroel Vehazmanim<\/b> by Rabbi Yisroel Dovid Harfenes<\/b>. The code available under the LGPL license can now be downloaded from the KosherJava Zmanim code repository<\/a>. Older stable releases can be downloaded from the download page<\/a>.
\nPlease note:<\/b><\/em> due to atmospheric conditions (pressure, humidity and other conditions), calculating zmanim accurately is very complex. The calculation of zmanim is dependent on Atmospheric refraction<\/a> (refraction of sunlight through the atmosphere), and zmanim can be off by up to 2 minutes based on atmospheric conditions. Inaccuracy is increased by elevation. It is not the intent of this API to provide any guarantee of accuracy. See Using a Digital Terrain Model to Calculate Visual Sunrise and Sunset Times<\/a> for additional information on the subject.<\/p>\n

How to Use the API<\/a><\/h3>\n

Information on how to use the API can be found on the How to Use the API page<\/a> as well as by reading the JavaDocs<\/a><\/p>\n

Zmanim Calendar Generator<\/a><\/h3>\n

A sample use of the API can be seen in the calendar generator<\/a>. This uses the Zmanim API to generate an annual Zmanim calendar in an Excel spreadsheet. Since this is a demo of the API, the calendar is generated using All (about 102 currently) possible zmanim that the API can generate.<\/p>\n

List of Zmanim Supported by the API<\/h3>\n

The API currently can generate about 157 different zmanim. Explanation of most of these can be seen by browsing the JavaDocs<\/a>. You can link to the documentation of the specific zmanim from the links below.<\/p>\n
